Comparing the clinical evolution of cystic fibrosis screened neonatally to that of cystic fibrosis diagnosed from clinical symptoms: a 10-year retrospective study in a French region (Brittany).

Until the year 2000, systematic cystic fibrosis (CF) neonatal screening was only performed in a few regions of France. The Brittany region began in 1989, but not the neighboring region of Loire-Atlantique. The present study compares the clinical evolution of both affected populations 10 years after screening was started. Although the 77 screened and 36 nonscreened children were followed in different CF centers, they were included in similar care protocols. The clinical characteristics at diagnosis and their evolution over a 10-year period of all the children affected with CF and born between January 1, 1989 and December 31, 1998, excluding those with meconium ileus, were compared. There were no significant differences in sex ratio, gestational age, anthropometric data at birth, frequency of deltaF508 homozygotes, proportion of pancreatic-insufficient patients, and mean age between the two populations. Age at diagnosis was lower in the screened group (38 days vs. 472 days, P < 10(-7)), as was the delay in supplementation with pancreatic enzymes (1.7 months vs.15.9 months, P < 10(-7)). The proportion of children who were hospitalized at least once was higher among the nonscreened than the screened patients (86% vs. 49%, P < 10(-4)). Z-scores for weight and height were significantly better in the screened population, not only in the first years of life, but also at 5 years old for height and 8 years old for weight. The Shwachman and Brasfield scores were higher among the screened children during the whole period of follow-up. No significant differences in colonization by Pseudomonas aeruginosa nor in lung function were found. Given the homogeneity in the characteristics and the follow-up of both populations, the benefits in terms of nutrition and clinical well-being of neonatal screening appear to be clear, thus confirming the advantages of its general implementation.

[Does neonatal screening of cystic fibrosis affect outcome? Comparative study of two cohorts in Britanny and Loire-Atlantique with follow-up after ten years].

UNLABELLED: Neonatal screening for cystic fibrosis was started in Brittany in 1989 but not in the adjacent department of Loire-Atlantique. This study compares the outcome from the children of both populations nine years after the beginning of the screening. Those children were seen in different centers but with the same following guidelines. POPULATION AND METHODS: All children with cystic fibrosis born between 01/01/89 and 31/12/97 in Brittany and the Loire-Atlantique, excluding the meconium ileus, were compared for their initial characteristics and their outcome after nine years of follow-up. RESULTS: There was no significant difference between both populations for sex ratio, gestational age, birth biometry, percentage of homozygotes delta F508, and mean age of children. Age at diagnosis was lower in Brittany (37 vs 372 days, P < 10(-7)), as was the delay for starting pancreatic supplementation (1.5 vs 14.3 months, P < 10(-7)). Percentage of children hospitalized at least once was higher in Loire-Atlantique (84.4 vs 40.3%, P < 10(-4)). There was no significant difference for colonization with Pseudomonas aeruginosa. Z-scores for weight and height were better in Brittany, as were Shwachman's and Brasfield's scores. CONCLUSION: The homogeneity of both populations and their follow-up points out that even if the numbers of children are small and the study is retrospective, some benefits of neonatal screening appear, which are already found in other countries where it is partly practiced. This leads us recommend its general use in our populations, which should be associated with the follow-up of the screened children in cystic fibrosis centers to achieve the most of its benefits.

Association of 1078 del T cystic fibrosis mutation with severe disease.

Apart from the high frequency of the delta F508 mutation (81.81%) in Breton cystic fibrosis chromosomes, one mutation, 1078 del T, is also observed frequently (4.96%) in this group, in comparison with the rest of the French where it occurs with a frequency of 0.57%. These two mutations account for more than 86.5% of the total CF mutations identified on Breton chromosomes. We have conducted an unblinded retrospective analysis of 25 patients with the 1078 del T mutation and compared their phenotypes with those of a group of 70 delta F508 homozygous patients. Both groups of patients had the same ethnic origin and were regularly attending the same CF centre in Brittany, which makes this sample highly homogeneous despite the small size. The 1078 del T mutation appeared to be associated with severe presentation of the disease with, however, a trend to reduced mortality and less Pseudomonas aeruginosa colonisation.

[Joubert's syndrome].

We report a new case of pathologically documented Joubert syndrome. A review of 35 published cases showed that this syndrome, first described by Joubert and Eisenring in 1969, is well individualized and exhibits consistent features, including attacks of tachypnea alternating with respiratory pauses, abnormal ocular movements, severe psychomotor retardation, and ataxia. Anatomic anomalies include vermian agenesis with cystic dilatation of the fourth ventricle. Inheritance of this condition is autosomal and recessive. Onset is in the neonatal period and prognosis is severe. Significant anatomic resemblances with the Dandy-Walker syndrome exist, although genetic and clinical features are different. The origin of this syndrome is unknown, but a study of peroxisomes is required since three cases of Joubert syndrome with pipecolic acidemia have been reported and resemblances exist between some recognized peroxisomal diseases and Joubert syndrome.
